  基于羧酸的小分子STAT3抑制剂的接头变异与结构-活性关系分析

  摘要：

  研究了已报道的苯甲酸（SH4-54），水杨酸（BP-1-102）和苯并异羟肟酸（SH5-07）的STAT3抑制剂的分子决定因素，以设计优化的类似物。所有三个导联均基于N-甲基甘氨酰胺支架，其两个胺基缩合成三个不同的官能团。甘氨酰胺支架的三个功能和CH 2基团分别进行了修饰。五氟苯或环己基苯的取代，或用杂环成分（含氮和氧元素）取代芳族羧酸或异羟肟酸基序的苯环，均会降低效能。值得注意的是，Ala-linker类似物1a和2v，以及在手性中心均具有（R）构型的基于Pro的衍生物5d在体外具有更高的抑制活性和针对STAT3 DNA结合活性的选择性，IC 50为3.0±0.9、1.80±0.94和2.4分别为±0.2μM。化合物1a，2v，5d和其他类似物在人乳腺癌和黑色素瘤细胞系中抑制STAT3组成型STAT3的磷酸化和激活，并在体外阻断肿瘤细胞的活力，生长，集落形成和迁移。基于专业的模拟，5h具

New dual inhibitors, of general formula, N-[2(R,S)-(mercaptomethyl)-3(R,S)-phenylbutanoyl]-L-amino acid with IC50 values in the nanomolar range for both enzymes were generated by this approach. The separation of the four stereoisomers using chiral amines and the stereoselective synthesis of the 2-(mercaptomethyl)-3-phenylbutanoyl moiety showed that inhibitors with the 2S,3R configuration

  在心血管疾病的治疗中，将由血管紧张素转换酶（ACE）引起的抑制血管紧张素II形成所产生的降压作用与由于保护血管内皮细胞而引起的利尿和利钠反应相关联可能具有治疗意义。上皮中性内肽酶（NEP）失活导致内源性心钠素（ANP）。但是，对该假设的研究需要一种能够共同抑制ACE和NEP的口服活性化合物。因此，基于两种酶的活性位点的特征，它们属于同一个锌金属肽酶家族，并根据其最有效和选择性的抑制剂的结构，通过合理的方法设计了双重抑制剂。由于NEP和ACE都包含较大的S'1-S' 选择能够容纳芳族残基的2个域，将环状ACE抑制剂3-（巯基甲基）-3,4,5,6-四氢-2-氧代-1H-1-苯并佐辛-1-酸丁酸作为模板。在有效的NEP抑制剂N- [2-（巯基甲基）-3-苯基丙酰基] -L-酪氨酸的苄基部分引入了各种脂肪族限制基团（IC50 NEP = 2 nM，IC50 ACE = 25 nM），以改善计算出
